Abstract AITranslate
As the world energy crisis and environmental pollution continue to intensify，the promotion of the clean energy revolution has become the direction of the world energy industry reform. Hydrogen energy is recognized as one of the clean energy sources to reduce carbon emissions and address fossil energy depletion. Hydrogen energy is the breakthrough of the energy revolution，and its development and utilization will certainly bring about significant changes in the energy structure. At present，hydrogen storage is the bottleneck in the application of clean hydrogen energy. Solid-state hydrogen storage has the advantages of high mass hydrogen storage density and low hydrogen storage pressure，which makes it an ideal way to store hydrogen. Solid rare earth alloy LaNi5 has the advantages of good toxicity resistance，easy activation，and fast hydrogen absorption and deposition at low pressure and room temperature，but the mass hydrogen storage density is lower than that of other room-temperature solid hydrogen storage alloys. AB5 solid hydrogen storage container，which has low and uniform stress，was effectively adapted to the heavy truck structure，realizing the special-shape of the hydrogen storage container and its integration with the carrier's chassis frame. At the same time，lightweight alloys were used to design the hydrogen storage container，realizing the lightweight of the integrated hydrogen storage system.Reducing the negative impact of low mass hydrogen storage density of AB5-type hydrogen storage alloys on integrated hydrogen storage systems.Under the same working condition，solid hydrogen storage containers made of Q345R，titanium alloy，6061 Al and LA103Z to be integrated with the heavy truck's chassis framewere designed. The integrated hydrogen storage system reduced thecentral core of the heavy truck by mounting solid-state hydrogen storage containers in the track's chassis frame. The barrel thickness of Q345R，titanium alloy，6061 Al and LA103Z solid-state hydrogen storage containers was 6，4，7 and 11 mm，respectively. The containers' weight was 24.4，9.2，9.9 and 8.7 kg，respectively. The mass hydrogen storage density of the system was 1.04%，1.23%，1.22% and 1.24%，respectively. Among them，the integrated hydrogen storage system with the tank made of LA103Z had the lightest mass and the highest hydrogen storage density，and the rare-earth hydrogen storage alloy with low mass hydrogen storage density had the least adverse effect on the hydrogen storage density of the integrated system. The integrated hydrogen storage designed mounts the hydrogen storage container in an unused space in the heavy truck chassis，taking up no additional cargo space. Without the integrated design，the solid-state hydrogen storage device saved the truck only 38.1 L·kg−1 H2 of cargo space compared to the 35 MPa cylinder. The integrated hydrogen storage system saved 62.5 L·kg−1 H2 of cargo space for the heavy truck compared to the 35 MPa cylinder，increasing the cargo space by 64.4%. Comparative analysis of integrated hydrogen storage systems based on rare earth lanthanide-nickel，titanium-iron，titanium-manganese，and vanadium-based solid solution materials forhydrogen storage at room temperature was carried out for the heavy Q345R tank. The integrated hydrogen storage system based on titanium-manganese alloy had the highest hydrogen storage capacity （30.5 kg）and hydrogen storage density （1.36%），and the integrated hydrogen storage system based on vanadium-based solid solution alloy was the most conducive to lightweight design. Hydrogen absorption and expansion of hydrogen storage materials generated large stresses （expansion stress） in the solid-state hydrogen storage container. This expansion stress was characterized by low weekly stress with long cycle time and high stress，which might lead to plastic deformation or even fatigue failure of the hydrogen storage container after many cycles. Therefore，it was necessary to consider the effect of expansion stress on the hydrogen storage system during hydrogen absorption and deposition. The stress-strain model of the hydrogen storage taking into account the volumetric and thermal expansion of the hydrogen-absorbing material in the tank was created. The stress-strain analysis of the solid-state hydrogen storage container was carried out using the finite element method，which comprehensively considered the hydrogen pressure inside the hydrogen storage container，the stress generated by the thermal and volumetric expansion of the hydrogen storage alloy in the process of hydrogen absorption and desorption，and the stress on the external surface of the hydrogen storage container. Stress concentration occurredbecause of discontinuity between the receiver and the head，and the maximum stress occurredat the connection between the receiver and the head. The analytical results showed that the maximum values of equivalent stresses of Q345R，titanium alloy，6061 Al and LA103Z hydrogen storage containers were 116.09，173.16，130.19 and 100.42 MPa，respectively，which did not exceed the tensile strength and yield strength of the material. To obtain specific stress values for the solid-state hydrogen storage container along the axial and radial directions and visualize the stress changes，paths were created in the radial and diameter directions. The maximum values of the equivalent elastic strain of Q345R，titanium alloy，6061 Al and LA103Z hydrogen storage container were 0.000599，0.00156，0.00213and 0.00246 mm·mm−1，respectively，and the strain maxima were in the micrometer scale.
